My invention relates to containers and dispensers for insecticides, fumigants and the like.

My invention contemplates the` provision of means for automatically dispensing and t maintaining suflcient insecticide and the like in a room or enclosure to kill or drive outv moths, flies and other insects and small animals. vWhile a large number of insecticides are elfective, for example, in protecting fabrics from moths, when present in suiiioient quantities, it becomes a problem to keep sufficient insecticide present at all times. The customary and usual method of dispensing these materials has been with a spraying or atoinizing pump whereby the fabrics are covered with a thin layer of the liquid and the surrounding air saturated therewith. But there is danger that the liquid may detrimentally affect the fabrics and, in addition, the air, which slowly circulates through the closets and storerooms, gradually removes the vapors. The handling of these insecticidal materials is particularly disagreeable because of its odor and volatile nature.

ll have aimed to provide a combined con tainer and dispenser for liquid insecticides whereby the necessity for dispensing and atomizing pumps is eliminated.

Jvii'iother object of my invention is to provide a container and dispenser for liquid insecticides requiring no pouring of the liquid from a container to a dispenser with the resulting 4inconvenience and odor.

A still further object of my invention is the provision of means for automatically dispensing the liquid whereby the saine is brought into contact with fabric only in the vapor form. a a

I have also aimed to provide a container for insecticides and the like which also serves as an automatic dispenser for the liquid when thc closure is perforated and the container inverted.

Other and important objects and attendant advantages will become evident to those skilled in the art from the description and drawings in whichi Figure `l is an eleva-tion of the container and dispenser attached to a wall in the dispensing position showing a portion of the support; i

Fig. 2 is a top view of the container and dispenserin the dispensing position;

Fig.`3 is a section on the line 3-3 of Fig. l showing in detail the dispensing well; and

Fig. 4 is a section on the line 4 4 of Fig. 3 showing the dispensing wall support.

The present embodiment of the invention comprises essentially a container or can of the usualA type havingl a dispensing wel-Il attached at the stopper and aimetal spring clam-p or holder into which the container is adapted to rest with the cap down and the well supported by the clamp. The clamp is designed to be fastened to base boards and the like by means of screws.

The container, which may be of any preferred construction, in the embodiment shown isa cylindrical metal can designated generally by 5. What is normally the bottom of the can is provided with a fia-t end 6 while the normal top is provided with a raised constricted top portion 7 having a threaded lip S and a circular central opening 9. A threaded metal cap l0 of the usual type screws over the threaded lip. In order, however, to adapt the ordinary cap to the invention a central opening ll is placed in the cap. A closure gasket 12 of the type usually used inV cans of this character is inserted between the cap and the lip of the can- These closure gaskets are usuallycomposed of one or more layers of cork or paper and a layer of lead foil, the foi-l facing the interior of the container. When the cap is screwed up tightly the cork or paper and lead are compressed between the cap andthe flange l?) on the threaded lip of the container top, providing an effective liquid seal.

A dispensing well support is connected to the can by means of the collar 14 which fits over the lip of the can and is held in position by the cap. Spoke-like portions 15 serve to connect the collar with a peripheral ring 16 having a iange 17 at right angles thereto adapted to receive the upper portion 18 of the dispensing well 19.

The well is made to be of the smaller diameter than the container and preferably of the same cross-sectional shape, the container, in its inverted position, serving to cover the well, preventing dirt and other particles from falling therein. Y' In like manner the well is positioned relatively close to thevcontainer. whereby air is permitted access to the liquid therein, but dirt is substantially excluded.-

The dispensing well, a circular shallow pan,

is held in its support through friction of the walls .17 and 18, the wall 18 extending against the peripheral ring 16 which extends inward from the Vwall to prevent the liquid from creeping over the edge of the well. Y Y

The dispenser is supported in use by a sheet metal holder or clamp comprising a central back strip 20 bent at right angles" near its lower end to provide a. bottom support 21 and having outwardly extending curved portions 22 intermediate its ends adapted to grip the container. The holder may be attached to the well orbase-board of a. room by means of tacks or screws 23. n

It will be evident that the handling and use of insecticides by means of my invention is unattended by the usual inconvenience and difficulty. The user or consumer receives the insecticide packed in the combined container and dispenser as a unit and no pouring from canto can is required. In the purchase of any-liquid the container is, of course, an essential part of the goods bought.

Y vThe manufacturer or distributor must necessarily furnish such a container and ,by-

. means of my invention he may, at a small additional cost, provide a container which also serves as` a. dispenser. I-Ie may use a standard container or can, readily and, cheaply obtainable on the market and, by slight adapt it for use according to my invention. A manufacturer now engaged in the distribution of such a product may adopt my invention without altering his present container in shape, size, or method of pack- Y ing. The container may be refilled if desired but lis-adapted to be discarded when empty to be replaced by a second container and dispenser lled with thek insecticidal liquid. The simplified container and dispenser leads to' improved results and does away with the necessity for a more expensive spray pump. i 'Ihe user receives the complete: assembly comprising the container with the insecticide substantially as shown in Fig. 1 readyI to be attached to the wall, base-board or other convenient support, byv means of the clamp, the

liquid being held in the can by the closure marked 12. In order to prepare the container for operation the clamp is attached to the wall, base-board, or other convenient support, the dispensing well is removed from its support by al slow twisting movement, and a small pointed object is inserted through the opening 11 in the cap, puncturing or perforating the closure 12 to form a hole therein approximately the size of the opening in the cap. The dispensing well is then replaced and the container inverted with a rapid movement. 'Ihe liquid flows into the dispensing well.until a level approximately Ias shownin Fig. 3 is reached where-the liquid in the well has reached the level of the opening in the closure. Here the flow is automaticallyvshutoif since the atmospheric pressure is sufficient to support the liquid in the container. The container and dispenser vis now placed in the holderwhere it may remainV untouched until the supply'of liquid is exhausted, for the liquid will automatically be fed into the well as evaporation proceeds.

'The dispenser needs no attention so long as the liquid lasts and lit insures that a fresh supply of vapors will continuously replace those escaping from the inclosure in which the device is used.

While I'have described afsingleembodi-i' ment of my invention it will be understood that numerous` modifications and changes may be made without departing from the spirit and scope of the invention and the appended claims.

I claim:

1. A combined container anddispenserr for insecticides comprising a container, a cap for said container having a small opening, a closure for said lcontainer resting within and secured by saidv cap adapted to be conveniently perforated through the opening in the cap, an evaporating well support having a central collar portionto be engaged by said capat a point between the closure and the container, spoke-like lportions; extending therefrom, a peripheral ring portion having a portion extending in the plane of the spokelike portions and a portion extending perpendicularly thereto, and an evaporating well frictionally held upon said perpendicularly extending portion of the support.

2. A combined container and dispenser for insecticides comprising a metal container, a metal screwkcap for said lcontainer having a small opening, a gasket between said cap and container normally liquid tight but adapted to be perforated through the openilo iis
